We Accompany You during the Changeover to the AS4 Protocol
The future of market communication: secure, flexible, and simple
Since 01.04.2024, the German energy market has taken a further step towards digitalization. The Applicability Statement 4 (AS4) protocol has become the technical standard for digital market communication (MaKo) and now ensures a higher security standard in data exchange. However, AS4 remains an important topic. The changeover phase for timetable management begins on 01.10.2024 and must be completed by 30.11.2024. From 01.12.2024, communication will only be permitted via the AS4 transmission path. Market communication for gas is also to be converted to AS4 on 01.10.2024. We are supporting the transformation of the energy market partners and allowing them to react flexibly to future implementation requirements.
The changeover so far has been a challenge for all market participants, raising questions and causing uncertainty. We, therefore, remain committed to ensuring that the changeover is as consistent and smooth as possible, and that the new market communication processes are as simple and automated as possible.
